PATENT SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 595,778, dated December21, 1897.

Application filed January 6, 1897. Serial No. 618,167. (No model.)

T0 all whom it may concern.-

Beit known that I, ERNEST A.KNVOOP, a citizen of the United States,residing at Monterey, in the county of Monterey and State of California,have invented a new and useful Nozzle for Spraying Water,Chemicals, and the Like, of which the following is a specification.

The object of my invention is to provide a nozzle by the u'se of whichinjury to hose may be avoided and by which plants may be watered withoutwetting the foliage.

My invention consists of a nozzle and a wire to which an adjustablestopper is connected.

It differs from other nozzles principally in the following respects,towit: First, the water under pressure is not forced through a contractednozzle, but is allowed to follow its course unchecked through a nozzleof even larger diameter than that of hose; second, the water in strikinga stopper after leaving the nozzle is spread in such a way that it fallsin a gentle umbrella-shaped sheet, thus preventing damage to plants;third, the nozzle is of sufficient length for the operator to reach theground, thus preventing any foliage from getting wet, if so desired;fourth, by reason of an adjustable stopper the water may be thrown as aline spray or as a jet to considerable distance; fifth,

in not checking the flow of water in the nozzle all the water which thehose will admit can be employed, thus saving much time.

In the accompanying drawings, Figure 1 is a broken side view of thecomplete nozzle in operation; Fig. 2, a detail view of the end of thenozzle with the stopper drawn in, so as to throw water as a jet. Fig. 3is a detail view with the perforated center plate of the stopper turnedfor the purpose of making a line spray. When so adjusted, it may be usedas a stationary lawn-sprinkler. Fig. 4 is a detail view with stopperdisengaged, allowing the water to flow out unobstructed. Fig. 5represents an end view of the mouth of the nozzle enlarged. Fig. 6 showsthe stopper enlarged, (without the wire,) giving the corresponding sizesand shapes of the three plates comprising the same. Fig. 7 is theenlarged center plate of the stopper, showing perforations and scallopededge, which aid in distributing spray. Fig. 8 represents side view ofthe enlargedv stopper with a wire passing through it.

The two outside plates of same are fastened to the wire, leaving middleone free torevolve.

lis a tube two or two and one-half feet long, preferably of brass. Theinside diameter is about one-eighth of an inch larger than that of thehose to which it is to be attached, thus reducing the pressure of waterto some extent before reaching the outlet.

2 is a flaring lip expanding the mouth of the nozzle by one-fourth thediameter of tube. The lip overlaps the detached portion of the end ofthe nozzle, so as to leave the -edges of said cut (represented by dottedlines in Fig. 2) 6 5 free, allowing water to pass out in a perfectlysmooth stream.

3 is awire sliding in clamps 5 5 5. The lower end has a turn long enoughto allow the stop-k per 4 to be drawn in past lip 2. It also has a 7ocrook 3', which prevents drops from running down the wire when thenozzle is held in elevated position.

4 4 4." are three metal-plates of different shapes and sizes comprisinga stopper which is intended to spread the water.

5 5 5 are clamps for holding the wire in position.

6 is a stirrup hinged to upper clamp and intended to catch in segments 3to hold the 8o stopper in any position.

7 is a metal tongue fastened to the wire to keep the same from turningas long as the former is under guide 8, which is fastened to the tube.

9 is a wire fastened to wire 3. It is in tended as a nger-hold tomanipulate the stopper or to stick into the ground when the nozzle isdesired as a lawn-sprinkler, as in Fig. 3.

10 is a coupling.

In Fig. 5, a is center of circle c g 't' h, representing end of the tubebefore any portion of the end has been removed. b, being inidway betweena and t, is the center of the 95 semicircle g k h with same radius, theintersection of which two circles marks the place where the out g i 7Lis taken out of the end of the tube in a flaring shape, as indicated bydotted lines, Fig. 2. This removed portion roo of the tube is aboutone-half of the diameterl of tube in length. g 7c 72, is an end view ofthe lip, which is not fitted in the cut, but must be soldered on so asto overlap, leaving the edges of the cut free to allow the water to passout in a perfectly smooth stream without coming in contact with the lip.In the construction of the mouth of the nozzle it must be observed thatafter cutting out the portion g i h the corners at g and h are pressedout so as to give the mouth an oval shape. Further, it is necessary thatthe mouth end of the lip should stand at right angles to the wire, whilethe end of the tube is cut in a slanting shape, as shown in cuts 1 2 34.

In Fig. 6, a is center of semicircle Z e m, with the same radins as a ein Fig. 5. Then taking e b as the radius, e is the center of thesemicircle Z b m, which two semicirclesv form plate 4, Fig. 8, which isfastened to the wire with c, almost touching the same in w. c, beingmidway between a and b, is the center of the semicircle Z f m, with aradius equal toae.

2o fis the center of the semicircle Zn m,with a radius equal to eb. Thelatter two semicircles form the movable plate 4, Fig. 8,which isperforated, as shown in Fig. Lujo. Plates 4 and 4" are of equal size. (Zis a hole through which the end of wire passes. It is midway between aand c. Plate 4" is in itslowerportion a trifle smaller than 4. The upperportion is cut out on a line running through center a in the mannershown in Fig. 6, fl' s and 0 p. t is a projection on plate 4 to stop thesame when turned, as in Figs. l or 3, by striking against the edges o sor op, respectively. Projection t must be equal in length to thedistance between a and c, commencing at the line running horizontallythrough a. The position of said plates must be at right angles to thetube, and in their position to the wire `@and g must almost touch thesame at w, Fig. 8.

In the practical use of my nozzle the stopper is brought to within aboutone-half inch of mouth, if a gentle spreading dow of water is desired.If water is to be thrown to adistance, as a jet, the stopper is drawn t0just a trie within mouth. Owing to the laring shape of lip, the distancemay be increased by drawing stopper in accordingly. If a fine spray isdesired, plate 4 is turned so as to offer a larger resistance. Thefarther the stopper is drawn in the iner willbe the spray. If no sprayof any kind is desired, the wire is pushed out until the tongue isreleased from under the guide, when the stopper may be disengaged byturning the wire.

I claim as my invention- A tube, having aborc oi uniform diameter, themouth of which is expanded by a flaring lip and into which is fitted amovable stopper, composed of one or more plates, substantially asdescribed and operated in the manner set forth.
